In Chrome, it is called “Incognito” mode whereas Firefox calls it “Private Browsing”; just to mention a few. Even though incognito browsing does have certain benefits, it still doesn’t fully maintain your privacy online. Anonymous search engines like “duckduckgo” and virtual private networks can help boost your online privacy; a story for another day.
